Problems solved by technology

However, the quality of each of the above-mentioned substrates is not equal, and when it is used in plug seedling cultivation, the effect is also uneven.
To sum up, there are mainly the following problems: one is that the matrix contains insufficient nutrients, and it is difficult to meet the needs of seedling growth during the entire seedling raising period, such as supplementing conventional compound fertilizers, i

Abstract

The invention particularly relates to a composite organic nursery substrate and a production method thereof. The substrate adopts leftovers of edible fungi and peanut shells as main materials, adopts peat, vermiculite, rice husk ash and attapulgite as accessories and adopts water retention agents, green fertilizers and ferrous sulfate as additives. The volume ratio of the main materials is 40-60:20-30 in sequence, the accessories are 5-20% of the main materials and the additives are in proper quantities. The production process of the substrate is as follows: decomposition pretreatment is carried on the main materials; the accessories and additives are added according to the volume ratio and are stirred evenly until the mixture passes test to be a qualified finished product. The substrate of the invention has good quality, rapid and neat emergence of seedlings, healthy plant growth and good water retention. The fertilizer efficiency can last for 30-50 days, enough for the growing development of the seedling stage, thus simplifying the management of labor power on plug seedling. Meanwhile, with good buffer action, the substrate can be widely applied to seedling culture of various organisms such as vegetables, flowers, cotton, rice, tobacco and nursery stocks, etc.

Description

technical field [0001] The invention relates to a soilless culture technology, in particular to a seedling-raising composite organic substrate and a production method thereof. Background technique [0002] In recent years, the soilless cultivation technology of factory seedlings has been widely popularized and applied. The material used for soilless cultivation in plug trays - the substrate is the key. A good matrix material must be conducive to the extension and attachment of plant roots; it can provide water, fertilizer, gas, heat, pH and other survival and development conditions for plant roots; it does not contain harmful and toxic substances that are unfavorable to plant growth; The buffering effect of physical and chemical absorption can dissolve foreign matter or harmful substances that may be produced by the root itself during the metabolic process, so that the environment for crop root growth is relatively stable; it is suitable for mass production operations and m...
